Background

Jason and his older brother Alex were raised in a bunch of different foster homes before a man named Ralph Harvey adopted them and began to follow in his beliefs about a corrupt government.

He was trying to convince the boys and his fellow members to change the system from within before he was arrested and jailed by the police for driving a car without a license. This act caused the McCann brothers to hate cops and seek revenge.

Season 11

Shock Waves

Jason sets his plan for revenge in motion by bombing a police funeral, resulting in the death of two officers.

The CSI's figure out that it is someone from community center and they show up as they are talking about Jason's adoptive father and a fistfight is started between the members and the police.

Later, he is taken into police custody for processing in connection to the bombing. He was later questioned by Stokes when his brother's print is found on a toy plane. Jason claims not to be involved with the bombs, that his brother is the bomber and tells Nick that he has a house in Henderson.

After Alex is killed, Jason kills a homeless man then drags the body to a secondary location where he sets two bombs, one under the man and the other in a tent next to where he killed him. When the CSI's are called to investigate Catherine sees through the first while Lou and Greg set off the other while coming out of it unscathed.

After this he was adopted by the leader of the community center, Paul Huxby and the case against him was let go. It is implied that Paul was abusive towards Jason, though this is unconfirmed.

Targets of Obsession

Jason reappears when he calls Nick as he walks toward his house. He tells Nick he deserves to die for what he did to his brother but nonetheless warns Nick that he can’t go home.

Nick stops just in time to avoid tripping a wire connected to a grenade. Jason is taken in for questioning where Nick speaks to Jason. He is asked several questions and gives Nick the false impression that he is in danger.

Their interview is interrupted when Dr. Paul Huxby shows up, Brass holds the man off for a minute, but eventually takes Jason away.

Then Jason kills Paul Huxby after Paul tries to convince him to stop the bombings. Unbeknownst to Paul, Jason has been using his identity to open a credit card in his name to buy supplies including explosives and a lease for a warehouse, all to set a trap in the warehouse for the three people who killed his brother with the help of a man named Timothy Johnson.

Nick, Catherine and Vartann go to the building with Kip the bomb tech, and they find Huxby’s body on the ground with

Jason watching on a video camera. The group finds the camera and then Catherine disables it with a laser quest.

Now blind to what is going on, when the bomb goes off he believes all of them are dead when in fact only one of them (Kip) is really dead.

Jason later recieves a call on his cellphone where he learns Nick is still alive and is angered by his taunting while is unaware they are tracking him down.

Jason argues with Johnson as they are driving away about how to handle the situation when they are stopped by the cops' roadblock and stop the van containing Jason and Johnson as they try to escape to California.

Johnson would rather give up than die, but Jason has other ideas. He yells that Johnson has a bomb on his body, and during the momentary confusion, Jason pulls out a gun and shoots one of the cops.

Nick and the others return fire, killing Jason in a hail of bullets.

Modus Operandi

The targets of Jason's bombings were always police officers. He used dead bodies as bait to attract law enforcement officials to a location where he proceeded to trigger the explosive devices. In the case of the first bombing, he used a body that was already dead (Officer Franklin Clark, who was killed in a shooting and was being buried). He late decided to create dead bodies himself, killing people using a blunt instrument. He would then lure the police to the bodies and attempt to blow them up. During the cemetery bombing, Jason used bombs that were detonated via cell phone that was contained in a remote-controlled plane he gave to Alex. He would later use bombs that were detonated by tripwires that cause a bomb ingredient, triacetone triperoxide, to fill said bombs and cause them to explode, but was stopped by the Las Vegas CSI before he could.
